Flew in from Atlanta on Airtran. No problems. Took the van shuttle to the Yellow Rose B&B. Shuttle cost: $16 (had $2 coupon), about $10 less than a taxi. The B&B was pleasant. The owners are helpful and are able to answer any questions you might have about SA. The housekeeper is very nice also. I enjoyed seeing the Riverwalk, the Alamo, and Market Square. I took the Trolley a few times and it is convenient and inexpensive. I also did a lot of walking.
The only negative about SA is that there is no grocery store dowtown. Where do people buy fruit? As a vegetarian, I had to search for acceptable places to eat. I did enjoy going to Azuca and Madhatters was OK.
All in all it was a good trip.
